What is the solution to the system of equations?

Mathematics
1 answer:
kow [346]4 years ago
7 0

Answer:

( -19,55)

Step-by-step explanation:

y=-3x - 2

5x + 2y = 15

+ First, we replace y = -3x -2 into 5x + 2y =15

and we have 5x + 2( -3x -2) =15

or 5x - 6x - 4 =15

or -x -4 =15

and -x -4 +4 = 15 +4

finally -x = 19, or x= -19.

Replace x = -19 into y = -3x -2 = -3*(-19) -2 = 57 -2 =55

The solution is (x, y) or ( -19, 55), we choose b)

Have a good day.

What is the value of x in the equation 1/2x - 3/4 = 3/8 - 5/8
Kitty [74]

The answer

x = 1

step by step

\frac{1}{2} x -  \frac{3}{4}  = \frac{3}{8}  -  \frac{5}{8} \\  \frac{1}{2} x = \frac{3}{8}  -  \frac{5}{8} +  \frac{3}{4}  \\  \frac{1}{2} x = \frac{3}{8}  -  \frac{5}{8} +  \frac{6}{8}  \\  \frac{1}{2}x =   \frac{4}{8}  \\  \frac{1}{2} x =  \frac{1}{2}  \\ x = 1
